Meghamalai, commonly known as the High Wavy Mountains, is a mountain range located in the Western Ghats in the Theni district near Kumily, Tamil Nadu. It is dotted with cardamom plantations and tea plantations. The mountain range is 1,500 metres above sea level, and it is rich in flora and fauna. The area, now mostly planted with tea plants, includes cloudlands, high wavys, venniar, and the manalar estates belonging to the Woodbriar Group. Access is largely restricted and includes largely untouched remnants of evergreen forest.
For a long time, there has been a pending proposal with the Tamil Nadu Forest Department to establish the Megamalai Wildlife Sanctuary on 600 km2 of forest in the division. The suggested priority tasks in the sanctuary include: the control of poaching, the use of pesticides for the elimination of ganja (Cannabis sativa) and the cultivation as well as scientific management of watersheds. The Megamalai Wildlife Sanctuary can be an excellent buffer to the Periyar Tiger Reserve and Grizzled Squirrel Wildlife Sanctuary which can immensely strengthen the conservation in the southern Western Ghats – the range of hills south of the Palakkad Gap.
